The invention discloses a beam forming device and method, comprising a radio frequency module and a main control module; the radio frequency module is connected with M vibration sources and N target terminals of a base station, and a control end of the main control module is connected with a controlled end of the radio frequency module The radio frequency module includes: a first phase-shifting unit, b second phase-shifting units and radio frequency cables, each first phase-shifting unit has M / a input ports and b output ports, and each second phase-shifting unit has M / a input ports and b output ports The unit has a input ports and N / b output ports, each output port of all the first phase shifting units is connected with one input port of each second phase shifting unit, the first phase shifting unit and the second phase shifting unit Both are connected with the main control module; the main control module is used to determine the horizontal adjustment phase and the vertical adjustment phase according to the received target beam angle, and send the horizontal adjustment phase to the first phase shift unit, and send the vertical adjustment phase to the second phase shifter. phase unit. The invention can solve the problems of complex and high cost of building a base station test environment.
Description
technical field [0001] The present invention relates to the technical field of wireless communication base station and terminal testing, and in particular, to a beamforming device and a beamforming method. Background technique [0002] The wireless communication base station has developed from 2 antennas to 8 antennas, and now has 64 antennas, and even 128 antennas. Massive MIMO (Massive MIMO) in wireless communication base stations is the core technology of 5G. In order to simulate and verify the performance of beamforming technology, a test solution that can realize ultra-large-scale multiple input and multiple output, beamforming and beam tracking is required. [0003] With the wide deployment of LTE+ (Long Term Evolution, long term evolution) and the gradual promotion of 5G, the industry has gradually solidified the test cases for base station equipment and terminal equipment, and the test volume has gradually increased. It is particularly important to improve the test e...
